A fulfilment centre is a facility that holds inventory and processes individual customer orders — picking single items, packing them, and shipping them direct to the person who bought them. It is the building behind an online order arriving at someone’s door.
Spelled fulfillment center in American English and fulfilment centre in British; the same thing either way, and frequently shortened to FC.
The distinguishing feature is the unit of work. A warehouse handles pallets. A distribution centre handles cases going to shops. A fulfilment centre handles individual items going to consumers, which is a far more labour-intensive operation and drives a completely different building layout.
How a fulfilment centre works
1. Receiving. Stock arrives in bulk from manufacturers or suppliers, is checked against the purchase order, and is booked in by scan.
2. Storage. Goods are put away into recorded locations, usually shelving and bins rather than pallet racking, because the pick unit is a single item. Many FCs use chaotic or random storage, where a product can live in several scattered locations and the system simply knows where — which sounds disorganised and packs space far more efficiently than grouping by product.
3. Picking. Orders arrive continuously through the day. Pickers work from handheld devices along optimised routes, usually picking several orders at once into separate totes — cluster picking. This is the most expensive activity in the building.
4. Packing. Items are verified against the order by scan, packed in right-sized packaging with appropriate protection, and labelled. The last opportunity to catch an error before it reaches a customer.
5. Shipping. Parcels are sorted by carrier and service, manifested, and staged for collection against cut-off times.
6. Returns. Goods come back, are inspected, and are routed to a disposition — back to sellable stock, to repair, to clearance or to disposal. Returns volumes in ecommerce are high enough that this is a core process rather than an afterthought.
The whole operation is built around order cut-offs. Everything sold before the cut-off must be picked, packed and staged before the carrier arrives, which is why fulfilment centres run on waves and why late release is the most common cause of late shipment.
Fulfilment centre vs warehouse vs distribution centre
| Fulfilment centre | Warehouse | Distribution centre | |
|---|---|---|---|
| Ships to | Individual consumers | Wherever the owner directs | Shops and business customers |
| Unit shipped | Single items, small parcels | Pallets | Cases and pallets |
| Order volume | Very high, continuous | Low | Moderate, scheduled |
| Order size | Small, a few lines | Bulk | Large |
| Primary purpose | Pick and ship individual orders | Store goods securely | Move bulk through quickly |
| Dwell time | Days to weeks | Weeks to months | Days |
| Storage type | Shelving and bins, often chaotic storage | Pallet racking | Racking plus large staging areas |
| Labour intensity | Very high — piece picking and packing | Low | Moderate |
| Returns | High volume, individual, core process | Rare | Bulk store returns |
| Packing | Every order packed individually | Minimal | Case and pallet level |
| Location logic | Near population centres and carrier hubs | Where space is cheapest | Near transport links, central to its region |
| Measured by | Orders shipped, cycle time, accuracy | Cost per unit held | Throughput |
The short version. A warehouse stores, a distribution centre moves bulk to businesses, and a fulfilment centre picks singles for consumers. The lines blur in practice — plenty of buildings do two of the three — and the distinction still matters when choosing a provider, because a building optimised for pallet flow performs badly at parcel picking.
The fulfilment models
In-house fulfilment. You hold stock and pick, pack and ship it yourself.
The case for it: complete control of quality, packaging and the unboxing experience; no per-order margin paid away; direct access to your own stock; and the ability to handle unusual, fragile or custom products however you choose.
The case against: space, staff, equipment and software all become your fixed costs, and they continue through quiet periods. Scaling means signing leases and hiring. Peak means finding temporary staff who need training.
It suits lower volumes, custom or fragile goods, and brands where the packaging is genuinely part of the product.
Outsourced fulfilment — fulfilment as a service, or a 3PL. A provider holds your stock and fulfils orders, charging per order, per unit and per pallet.
The case for it: capacity that flexes with volume without leases or hiring; better carrier rates than you could negotiate alone; someone else’s problem at peak; and geographic reach without building anything.
The case against: you pay per order, you lose direct control, and their errors reach your customer with your name on them.
It suits most growing product businesses past the point where packing in-house is eating time and space. How to choose a 3PL covers the selection.
Hybrid. Core lines in-house or at a 3PL, the long tail dropshipped, overflow handled elsewhere at peak, or different regions served by different providers.
The case for it: control where it matters and cost efficiency where it does not. The most common arrangement for businesses past a certain size.
The case against: two or more systems to reconcile, and inventory data that must stay consistent across them — which is where omnichannel fulfilment becomes a real requirement rather than a nice idea.
Amazon fulfilment centres and FBA
Amazon operates one of the largest fulfilment networks in the world, and sellers can use it through Fulfilment by Amazon.
How it works. You send your stock into Amazon’s fulfilment centres. When an order is placed — on Amazon, and optionally on your own channels through multi-channel fulfilment — Amazon picks, packs and ships it, and handles customer service and returns for those orders.
Why sellers use it. Prime eligibility, which lifts conversion substantially on Amazon; the buy box advantage, which matters enormously on shared listings; and the removal of fulfilment work entirely.
What it costs. A fulfilment fee per unit driven by size and weight, plus monthly storage charged by volume, plus long-term storage surcharges on anything that sits, plus returns processing. The fees are the reason the model works well for small, light, fast-moving products with enough margin, and badly for bulky, heavy or slow-moving ones.
The trade-offs. You lose control of packaging and the unboxing experience, your stock sits in a network you cannot visit, and stock that stops selling accrues storage charges until you pay to remove it. Preparation requirements are strict, and getting them wrong causes delays at intake.
There is a fuller treatment, including the calculation of whether FBA pays for a given product, in what is FBA.
The benefits of using a fulfilment centre
No warehouse to run. No lease, no racking, no equipment, no fulfilment software to buy and maintain.
Capacity that flexes. Volume doubles and the provider absorbs it. Volume halves and you are not paying for empty space.
Better shipping rates. Providers negotiate carrier rates across all their clients’ volume, which is usually well below what an individual business can achieve.
Faster delivery through proximity. Holding stock in two or three regional fulfilment centres puts goods closer to customers without building anything.
Peak handled. December volumes that would overwhelm your own setup are routine for a provider who has staffed for them.
Expertise and systems included. Warehouse management software, carrier integrations and pick processes that already work.
Your time back. For a small team, the hours spent packing are hours not spent on product, marketing or customers — and that is usually the real argument rather than the cost comparison.
Technology and integrations. A fulfilment centre runs on a WMS that directs picking and records every movement, connected to wherever you sell so orders flow in automatically and stock figures flow back. That connection is what prevents overselling, and it is the first thing to test when evaluating a provider — ask which of your specific platforms are already supported as standard products rather than accepting a general assurance that they integrate with anything.
Is a fulfilment centre right for your business?
The signs you should outsource:
- Packing orders is consuming serious time or space
- You are turning down growth because you cannot physically fulfil it
- A seasonal peak overwhelms you every year
- You want stock closer to customers in a new region
- You are about to sign a warehouse lease or hire your first warehouse staff
- Your own error rate is affecting reviews or returns
The signs you should keep it in-house:
- Order volumes are low enough that per-order fees outweigh the convenience
- Your product needs specialist handling a general provider cannot offer
- Packaging and presentation are genuinely part of what customers buy
- You customise or personalise orders
- Fulfilment is your competitive edge
The honest test. Price your own fulfilment properly — including your time at what it is actually worth, the space it occupies, the packaging, and the shipping rates you personally get — and compare it against a provider’s quote for a real month of your orders. Businesses that do this arithmetic honestly are frequently surprised in both directions.
And a note on timing. Moving fulfilment is disruptive, so the worst time to do it is under pressure. If you can see the crossover coming, move before the peak rather than during it.

The one-line takeaway
A fulfilment centre holds stock and ships individual orders direct to consumers, which makes it far more labour-intensive than a warehouse and laid out completely differently — shelving rather than racking, piece picking rather than pallets, and returns as a core process. Whether to use one comes down to pricing your own fulfilment honestly, including your time, against a provider’s quote for a real month of your orders.
Frequently asked questions
What is a fulfilment centre? A facility that holds inventory and processes individual customer orders — picking single items, packing them and shipping them direct to consumers. It also handles the returns those orders generate, which in ecommerce is a substantial part of the work.
What is the difference between a fulfilment centre and a warehouse? A warehouse is built to store goods, usually on pallets, for weeks or months, and is measured by capacity and cost per unit held. A fulfilment centre is built to pick and ship individual items continuously, uses shelving and bins rather than racking, and is measured by orders shipped, cycle time and accuracy.
What is the difference between a fulfilment centre and a distribution centre? A distribution centre ships cases and pallets to shops and business customers on a schedule. A fulfilment centre picks single items and ships small parcels to consumers as orders arrive. The unit, the destination and the order pattern all differ, which is why the buildings are laid out differently.
What is an Amazon fulfilment centre? One of the facilities in Amazon’s fulfilment network. Sellers using Fulfilment by Amazon send stock in, and Amazon picks, packs, ships and handles customer service and returns — which gives Prime eligibility and a buy box advantage in exchange for per-unit fulfilment fees and volume-based storage charges.
What does a fulfilment centre do? Receives stock in bulk, stores it in recorded locations, picks individual items against incoming orders, packs and verifies them, sorts and ships by carrier against cut-off times, and processes returns back into sellable stock or another disposition.
Should I use a fulfilment centre or fulfil in-house? Outsource when packing is eating serious time or space, when peaks overwhelm you, or when you want stock closer to customers in a new region. Keep it in-house when volumes are low, when the product needs specialist handling, or when packaging and presentation are genuinely part of what customers are buying.
How much does a fulfilment centre cost? Typically receiving per pallet or carton, storage per location per week or month, a pick and pack charge for the first item plus a lower charge per additional item, packaging, shipping at their carrier rates, and returns per item. Because structures differ between providers, compare them by having each price a real month of your own orders rather than by headline rates.
